2169 - Count Operations to Obtain Zero\.
Easy
You are given two non-negative integers
num1
andnum2
.In one operation , if
num1 >= num2
, you must subtractnum2
fromnum1
, otherwise subtractnum1
fromnum2
.For example, if
num1 = 5
andnum2 = 4
, subtractnum2
fromnum1
, thus obtainingnum1 = 1
andnum2 = 4
. However, ifnum1 = 4
andnum2 = 5
, after one operation,num1 = 4
andnum2 = 1
.
Return the number of operations required to make either
num1 = 0
ornum2 = 0
.Example 1:
Input: num1 = 2, num2 = 3
Output: 3
Explanation:
Operation 1: num1 = 2, num2 = 3. Since num1 < num2, we subtract num1 from num2 and get num1 = 2, num2 = 3 - 2 = 1.
Operation 2: num1 = 2, num2 = 1. Since num1 > num2, we subtract num2 from num1.
Operation 3: num1 = 1, num2 = 1. Since num1 == num2, we subtract num2 from num1.
Now num1 = 0 and num2 = 1. Since num1 == 0, we do not need to perform any further operations.
So the total number of operations required is 3.
Example 2:
Input: num1 = 10, num2 = 10
Output: 1
Explanation:
Operation 1: num1 = 10, num2 = 10. Since num1 == num2, we subtract num2 from num1 and get num1 = 10 - 10 = 0.
Now num1 = 0 and num2 = 10. Since num1 == 0, we are done.
So the total number of operations required is 1.
Constraints:
<code>0 <= num1, num2 <= 10<sup>5</sup></code>
